Neuquén Province
Neuquén () is a province of Argentina, located in the west of the country, at the northern end of Patagonia. It borders Mendoza Province to the north, Rio Negro Province to the southeast, and Chile to the west. It also meets La Pampa Province at its northeast corner. History The Neuquén Province receives its name from the Neuquén River. The term ''"Neuquén"'' derives from the Mapudungun word ''"Nehuenken"'' meaning ''drafty'', which the aborigines used for the river. The word (without the accentuation) is a palindrome. Lácar Department in Neuquén Province has the southernmost known remains of maize before it was further diffused by the Inca Empire. Maize remains were found as far south as 40°19' S in Melinquina, with it being found inside pottery dated to 730 ±80 BP and 920 ±60 BP. This maize was probably brought across the Andes from Chile. Inhabited by Tehuelches and Pehuenche, the territory was initially explored by conquistadores coming from Chile. In 1670 a Jesu ...

Limay River
The Limay River is an important river in the northwestern Argentine Patagonia (the region of Comahue). It originates at the eastern end of the Nahuel Huapi Lake and flows in a meandering path for about , collecting the waters of several tributaries, such as the Traful River, the Pichileufú and the Collón Curá. It then meets the Neuquén River and together they become the Río Negro. At this confluence lies the city of Neuquén. The river serves as natural border between the provinces of Río Negro and Neuquén. Its deep waters are clear, and carry a large flow, on average. Its drainage basin has an area of and includes almost all the rivers and streams of the Atlantic basin in the region, as well as an extensive network of lakes. The waters of the Limay are used to generate hydroelectricity at the five dams built on its course: Alicurá, Piedra del Águila, Pichi Picún Leufú, El Chocón, and Arroyito; together with the Cerros Colorados Complex on the Neuquén River ...

Río Negro (Argentina)
Río Negro (; ''Black River'') is the main river of Patagonia in terms of the size of its drainage basin, its associated agricultural produce and population living at its shores. In eastern Patagonia it is also the largest by flow rate. The river flows through the Argentine province of Río Negro which is named after it. Its name comes from the literal translation of the Mapuche term ''Curu Leuvu'', although the water is more green than black. Formerly, it was also known as "river of the willows" because of the big number of weeping willows that grow along the bank. It is 635 km in length. It originates from the junction of the Limay River and Neuquén River at the border with the Neuquén Province, and flows southeast incised through steppes to the Atlantic Ocean at , near El Cóndor beach resort some downstream from Viedma, Río Negro province's capital. The river allows the Río Negro province to produce 70% of the pears and 72% the apples of Argentina. The main area o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Chimehuin River is a river in the northwest of the Patagonic Province of Neuquén, Argentina. Its origin is at Lake Huechulafquen and it passes by the city of Junín de los Andes. After a course of about 53 km, it merges with the Aluminé River to form the Collón Curá River. The Chimehuin is considered a prime spot for fly fishing. It is known for its two introduced species of Salmonidae, the brown trout and the rainbow trout. The area around first part of the river's course (from the lake up to a few kilometers before Junín de los Andes) is a protected nature reserve (''Área Natural Protegida Boca del Chimehuin'').INTA Inta (russian: Инта́, kv, Инта) is a town in the Komi Republic, Russia.

Collón Curá Formation
The Collón Curá Formation ( es, Formación Collón Curá) is a Middle Miocene fossiliferous geological formation of the southern Neuquén Basin in northwestern Patagonia and the western Cañadón Asfalto Basin of central Patagonia, Argentina. The formation crops out from the southern Neuquén Province, the western Río Negro Province to the northern Chubut Province. The formation, with a maximum thickness of , comprises tuffs and sandstones with minor siltstones, marls and limestones, deposited in a fluvial, river delta, deltaic and shallow to deep lacustrine depositional environment, environment in small basins separated by Fault (geology), faults. The formation dates from the Langhian to Tortonian, earliest Tortonian epochs of the Middle to Late Miocene, typically Colloncuran. The Collón Curá Formation is named after Estancia Collón Curá (1 on the map in the infobox) along the Collón Curá River (2), a tributary of the Limay River in the Río Negro (Argentina), Río Negr ...

South American Land Mammal Age
The South American land mammal ages (SALMA) establish a geologic timescale for prehistoric South American fauna beginning 64.5 Mya (unit), Ma during the Paleocene and continuing through to the Late Pleistocene (0.011 Ma). These periods are referred to as ages, stages, or intervals and were established using geographic place names where fossil materials where obtained.Flynn & Swisher, 1995 The basic unit of measure is the first/last boundary statement. This shows that the first appearance event of one taxon is known to predate the last appearance event of another. If two taxa are found in the same fossil quarry or at the same stratigraphic horizon, then their age-range zones overlap. Background South America was an island continent for much of the Cenozoic, or the "Age of Mammals". As a result, its mammals evolved in their own unique directions, as Australia and Madagascar still have today.

Colloncuran
The Colloncuran ( es, Colloncurense) age is a period of geologic time (15.5–13.8 Ma) within the Middle Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America.

Etymology The age is named after the Collón Curá Formation in the Cañadón Asfalto and Neuquén Basins of northern Patagonia, Argentina Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America.

Birdwatching
Birdwatching, or birding, is the observing of birds, either as a recreational activity or as a form of citizen science. A birdwatcher may observe by using their naked eye, by using a visual enhancement device like binoculars or a telescope, by listening for bird sounds, or by watching public webcams. Most birdwatchers pursue this activity for recreational or social reasons, unlike ornithologists, who engage in the study of birds using formal scientific methods. Birding, birdwatching, and twitching The first recorded use of the term ''birdwatcher'' was in 1901 by Edmund Selous; ''bird'' was introduced as a verb in 1918. The term ''birding'' was also used for the practice of ''fowling'' or hunting with firearms as in Shakespeare's '' The Merry Wives of Windsor'' (1602): "She laments sir... her husband goes this morning a-birding." The terms ''birding'' and ''birdwatching'' are today used by some interchangeably, although some participants prefer ''birding'', partly because it ...
